low pH problems
Grrrowerstarted grow question 5y ago
I discovered that I had irrigated with water at pH 3.5 for at least 5 days.
yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?

I think the only way to know is to check the runoff when watering and see what PH it gives you.. if it's in an ok range, then just leave it (don't try to compensate), as the damage was done and you don't want to push it the other direction, possibly making it worse.. the marks on the leaves will not recover, but check the new growth to ensure that this is fine moving forward.
If you're in soil, i'd rather err on the higher side, so around 6.3, as 5.7/5.8 is more for hydroponics..

Hi I would flush the whole thing to make sure :-). Adjust the Ph and Ec value of the water and rinse it :-) to luck you have it right on time :-)

damage was done, so you could expect some minor burning. As long as you adjust the ph, all should be grand. In soil growing the pH is getting alkaline with the drying of the soil between watering. That is why you have to water well until you get a run off in the tray, to flush out the alkalinity from the middle of the root ball. Don't get over stressed about the pH in the water or to have it at just the right value. Plant will do just fine with water pH 7.

DWC water change or NOT?DWC - The DWC smells good, there are no signs of rot or foul smells - I use 3% H202. I keep the temps under 22. The plants are doing great. Should I just add in my flowering nutrients and let it keep running, or should I disinfect and do a full change? Thanks in advance!Week 3

Feeding advice.What should I feed? I'm 2 weeks into my second attempt at a first grow lol. I'm growing an Auto in soil, outdoors in the UK.
I'm trying to keep things organic. I've researched rabbit manure which I have and liquid seaweed. When can I use these? Do I need them?

Can I go back to nutes after flushing?I have a 70L res with 3 plants in it. 2 of them are the same, the third is a strain with 10-20 days shorter flowering time. I'll have to flush her before the others are ready. Can I flush all 3 at once for a week, then chop down the one and then add nuts to the other for a week?Feeding. Other

How early do you normally start feeding? Currently growing only autos. Have had great results with my grows so far, but always room for inprovement.I typically wait 4-6 weeks before I start adding any sort of nutrients as I used Fox Farms Happy Frog for my grows. How early do you start feeding? I have Micro, Grow, Bloom, Calnesium, Carbo Blast and all three of the bloom nutes which are irrelevant to my question

Adding Bloom NutesI'm thinking about adding either Overdrive or Big Bud to the nutrient list so my question is two fold. I think I have probably 4-5 more weeks of flowering is it worth it to add more nutes now? I would also appreciate anyone's opinion on using these independently vs together.Week 7

Verrouillage des nutriments ? Quantité d’eau ?Les plantes ne semblent pas aller bien. J’ai une décoloration sur les bouts des feuilles et sur certaines, les feuilles pointent vers le bas, elles ne stretchent presque pas, je pense à un Nutrient lockout, qu’en pensez-vous ?
Quelle quantité d’eau devrais-je arroser à 33 jours ?

When to stop veg nutes and start bloom nutes?Hi all! My Alien Moonrocks autoflower is 36 days old and is just starting to flower. She has just begun stretching (which I know uses a lot of nitrogen) so I'm wondering how long I should continue giving her veg nutes and when I should start giving her bloom nutes?Week 5

First time testing PPM and slightly panicked :cRunoff was at 2200PPM. I flushed her with 5L of pH 5.8 water. I got the runoff to 1000PPM where I left it. The pH was at 7 though and was higher than before the flush. Why is that? I always pH before watering. Also, is the flush going to cause trouble for her? I kind of panicked.5y ago

Forgot to alter pHHi I forgot to alter the pH. I already have some issues (I think pH? Check picture). What’s worse, overwatering or too high pH? Do I need to flush ASAP or wait till next watering cycle? The pH of the water I used is 7,7 and I have organic potting soil so is it a big deal or not?
